Suture clips, delivery devices and methods

ActiveUS20070093858A1Enhancing suture capturing effectRemoval from surfaceSuture equipmentsHaberdasheryTwo stepEndoscope
Suture clips and suture clip loading, delivery, locking and severing devices in both catheter and endoscopic embodiments are disclosed that permit the delivery and application of suture clips directly in contact with or in close approximation to sutured tissue. The catheter or endoscopic versions incorporate a collet cage with a plurality of flexible collet fingers that captivate a suture clip ring and a suture clip plug for assembly with a suture. An outer sliding sleeve constrains the collet fingers when distally advanced to minimize potential trauma during delivery and assembly of the suture clip in close proximity to the stitched tissue. Proximal retraction of the sliding sleeve coupled with the distal advancement of a pusher against cam surfaces on the inner walls of the collet fingers causes the collet fingers to open. The catheter is designed to hold and assemble the suture clip in a first position and release the suture clip and sever the suture ends proximal to the suture clip in a second position. Single pusher two-step embodiments and double pusher three-step embodiments are disclosed. Suture clip designs with plugs having heads for use with the suture clip delivery catheter are also disclosed. A suture clip loading device for loading suture clip components into the delivery system as well as a threader for threading sutures into the suture clip systems are also disclosed. A method of loading, delivering and deploying suture clips is further disclosed.

Suture clip applier

ActiveUS20110087242A1Suture equipmentsWound clampsLaparoscopyOpen sutures
Suture clip appliers, suture clips and methods of their use for securing sutures during an endoscopic or laparoscopic procedure are provided, wherein the method includes the steps of providing a suture clip applier having a working tip configured to retain and fire a suture clip; providing a suture clip having a biased closed configuration; loading the suture clip into the working tip of the clip applier; translating the suture clip distally relative to the working tip to a first position wherein the suture clip is splayed open; inserting a suture into the opened suture clip; and translating the suture clip distally relative to the working tip such that the suture clip is ejected from the working tip and biased to the closed configuration to close on and to retain the suture.

Double-arm suture clip capable of closing wound surfaces

The present invention relates to the field of medical devices and particularly relates to a double-arm suture clip capable of closing wound surfaces. The double-arm suture clip comprises a control assembly, and an upper suture clip assembly and a lower suture clip assembly arranged oppositely on the control assembly, and further comprises a sleeve. The upper suture clip assembly and the lower suture clip assembly each comprise a clip plate, a clip head, a front positioning pin and a rear positioning pin, the clip plates pass through both ends of the sleeve, the front positioning pins and the rear positioning pins are respectively arranged at both ends in the sleeve, and one end of each clip head is arranged on the corresponding clip plate. During use of the double-arm suture clip capable of closing the wound surfaces, release notches in the clip plates cooperate with clinch bolts on the clip plates, at the same time, when sliding rings are pulled, one end of a connector slides in a fixed seat and applies a reverse force to the sleeve, the reverse force forces the connector to separate from the sleeve, and at the same time connection places of the clip plates and clip heads also have a reverse force, so that the release notches of the clip heads release out the clinch bolts on the clip plates under the reverse force.
